12 Claims.

This invention relates to a paper winding rnachine. The invention is useful in connection with the winding of any kind of web material upon mandrels, etc. To simplify the description of the machine, the machine will be described as employed for the winding of paper in rolls.

An object of the invention is to provide a web or paper winding machine which greatly facilitates the removal of mandrels containing the wound material and the insertion of new mandrels, etc. A further object is to provide a structure in which a horizontal shaft is vertically movable through a mandrel supporting spider equipped with means for releasably securing'the shaft to the spider at any desired elevation. A further object is to provide in such a structure means for elevating the spider and/or shaft structure and for rotating the same to move the filled mandrel to an elevated position for removal while directing an unfilled mandrel into position for winding the web thereon. Yet another object is to provide over a pair of parallel winding rolls a vertically guided floating shaft structure, movable vertically within a spider and adapted to be releasably clamped thereto, a rider roll being carried by said shaft and mandrels being carried between the ends of said spider. Yet another object is to provide with the above structure power means for elevating the shaft andthe spider clamped thereto and for supporting the same in an elevated position for rotation well above said parallel rolls. Yet another object is to provide in such a structure guide means for maintaining said spider in a vertical position while paper is being wound upon the lowermost mandrel, elevating means being provided for lifting said spider free of said guide means to permit rotation of the spider upon the shaft clamped thereto. -A still further object is to provide in a paper-winding machine spaced driven rolls for winding paper upon a oating mandrel and in combination with a severing device and a tucker for securing the paper about the winding mandrel, spider means being provided for raising the filled mandrel and inserting a new or unfilled mandrel in its place. Other specific objects and advantages will appear-'as the specification proceeds.

The invention is shown in an illustrative embodiment by the accompanying drawings, in which- Figure 1 is a perspective view of a machine embodying my invention; Fig. 2, a broken vertical sectional view; Fig. 3, a broken longitudinal sectional view;l and Fig. 4.a perspective view of the clamping parts shown in spaced-apart relation.

In the illustration given, II) and I I designate side walls for the machine, each of said side walls or frames being provided near its top with a vertical slot I2. Adjacent the top of the slot on the inner side of the side walls are short, spaced guides I3. I

Much of the machine is of old and Well-known construction and need be referred to but briefly. For example, the machine is provided at its rear with a base support I4, on which is mounted the shaft I5 supporting the paper supply roll I6, as shown more clearly in Fig. 2. v'The paper Il from the roll I6 extends inwardly about a guide roll I 8 and thence around a bedroll I9 and is wound about a mandrel 2Q. Cooperating with the bedroll I9 having longitudinal and annular recesses therein, are the perforating roll 2l and slitting roll 22. variety of other operations may be carried on in connection With the bedroll I9 by various types of cooperating rolls, slitters, perforators, etc.V

The mandrel 20 upon which the paper is wound is supported in a oating relation upon the roll I9 and a second roll 23 supported in parallel relation with roll I9 and driven in the same ,direction. The two parallel rolls ISand 23 have their inner .adjacent surfaces substantially aligned with the vertical slots I2 in the side walls I6 and II of' the frame, and they serve as winding rolls for winding the paper about the floating mandrel 20. A rotatably-mounted shaft 2li is equipped witha curved arm 25, on which is mounted a knife 26 and atucker 2l. After the completion of the winding of paper upon the mandrel 2S, the 'knife 26 is swung inwardly to sever the paper, `and similarly when the paper is to be tucked about the mandrel 20, this is accomplished by the swinging forwardly of the tucker 2l on lever 25. Since theslitting, perforating, severing and tucking devices are old and well. understood in the art, a detailed description herein is believed to` be unnecessary.

A shaft 28 extends through the slots I2 of the side walls I0 and Il, as shown best in Fig. 3. A spider 29 is provided with vertically-slotted end Walls 3i) receiving ,the shaft 28. The end-plates Silsupport at each end a mandrel 20, the lowermost mandrel being in a position for the windlng of paper thereon as heretofore described. Any means for supporting the mandrel 20 rotatably upon. the spider vplate ends may be provided. In the specific illustration given, a bearing 3i is provided with Va cup-like end 32 for rNlf OFFICE It will -be understood Vthat a I claim: l.
